FIELD

The present application relates generally to computers, and computer applications, and more particularly to mobile device applications and converting existing web sites as mobile applications.

BACKGROUND

A mobile application (also referred to as mobile app) refers to a software application that is run on a mobile device. Existing web sites are usually developed for access by a desktop computer or the like with full capacity to screens, networking bandwidth, connection, and others. For at least those reasons, accessing those web sites from a mobile device (e.g., those that might experience network disconnects or loss as the device moves from one area to another, narrow bandwidth, and other characteristics inherent in mobile devices) proves to be inefficient.

As another aspect, a mobile app is deployed into an application store such as an “App Store”, when it is created. Whenever any updates are needed to be done to the mobile app, the entire updated mobile app is loaded back into such application store. Once the mobile app is updated on the application store, the entire application is then downloaded to the mobile device and reinstalled. Current known methodologies do not allow for selective updates, it is not possible to perform partial updates of an application using known solutions.

BRIEF SUMMARY

DETAILED DESCRIPTION

In one embodiment of the present disclosure, a methodology is presented that enables users or customers of a web site or the like (e.g., client/server application), for example an existing web site, to create a mobile web site. For instance, the methodology of the present disclosure in one embodiment may provide for the mobile enablement of the existing web server or application server (e.g., WebSphere™) customers that already have investments in traditional Internet Web Sites. In one aspect, the methodology of the present disclosure may create a mobile web site from the JavaServer Pages (JSPs) of an Internet Web site.

The methodology of the present disclosure in one aspect converts an existing Internet Web site into a functionally equivalent “mobile client and mobile gateway” so that the Web site can be accessed and used efficiently via mobile devices. Examples of a mobile device may include, but not limited to, a cell phone, smart phone, tablet, laptop computer, and/or others. Consider a conventional Web site, created via tooling like Eclipse™. Here the web site is composed of one or more JSPs. In one embodiment of the present disclosure, a plugin for Eclipse™ is created that reads the JSP pages from the web site above and renders the hypertext markup language (HTML) for each page into a file. Within this HTML the navigational links between these pages are changed to local links. In addition, the associated JSPs are analyzed to determine which items on these HTML pages are dynamic data. Dynamic data or dynamic content refers to data whose values are obtained for displaying on a web page, e.g., as opposed to having the data value pre-specified in the HTML page. Dynamic data, e.g., may be caused to be displayed via a scripting language, e.g., embedded in the web page. So for example, a dynamic web page includes dynamic content that changes, e.g., based on user input, attributes or parameters, computer program, and/or another criterion. The methodology of the present disclosure in one embodiment modifies these JSPs to create a new set of JSPs that offer RESTful interfaces to the logic for each dynamic tag. REST stands for Representational State Transfer. This new set of HTML pages is called the mobile gateway for the web site. These tags, and their associated RESTful interfaces, are correlated with their companion dynamic tags within the HTML pages above. Next, the dynamic tags in the HTML are replaced by RESTful calls to the RESTful interfaces of the mobile gateway.

To create a mobile app the HTML pages are packaged collectively into a bundle with an icon and an interface to the “web browser” for the operating system (OS) of the mobile device. This collection constitutes a mobile app, which is deployable to an application store or the like, e.g., the iTunes™ App Store™, and other application stores. An application store refers to an online store for downloading software applications and/or mobile applications, e.g., by purchasing or free of charge.

A more sophisticated mobile app has embedded within this package a local JavaScript based client side aggregator. This aggregator batches requests from the mobile application for dynamic content and sends them to the mobile gateway in a single message. This greatly reduces network chatter and bandwidth by assembling multiple requests for dynamic data into a single request. It receives back a single response which the aggregator breaks into separate responses, one for each originating request.

Once the app is deployed to an application store it can then be downloaded to a mobile device. The app's icon is displayed on the device's home screen, and clicking on this icon will evoke and display the corresponding HTML pages on the mobile devices screen. Within these HTML pages the associated dynamic data is fetched from the respective mobile gateway. In one embodiment of the present disclosure, this is achieved via the embedded RESTful commands or the like.

Navigation among the HTML pages in an app occurs locally and thus requires no network access. This reduces network traffic and thereby improves the user experience. As each page is displayed the dynamic data for that page is fetched. There is no need to fetch either the pages HTML or JavaScript because they are already loaded onto the mobile device as part of the app. This saves network resources, makes the gateway more scalable and further improves the user experience.

The HTML and JavaScript are part of the app and are thus not fetched over the cellular network. This reduces network traffic and the load on the server. This is particularly valuable if the HTML pages include JavaScript for analytics. Dynamic data is fetched via restful means. Thus the link between the mobile client and the server is asynchronous and is thus well suited to surviving network disconnects and adapting to power saving protocols where the app is put to sleep. Using standard mobile OS techniques the app is awoken when a message is received from the server. Using restful messages is both network friendly and resource efficient. Having the HTML graphical user interface (GUI) local on the client improves the apps responsiveness to manipulation by the user. The mobile gateway provides the app with restful interfaces to the back end data. These interfaces are both network friendly and resource efficient. Multiple request for dynamic data from the app can be aggregated together to minimize the number of messages (and the amount of data) flowing over the network. This reduces the network latency experienced by the user.

A methodology of the present disclosure in one embodiment converts existing web site to a mobile friendly one that may include a mobile client and a mobile gateway. The gateway here may be a server that houses the RESTful interfaces and connectors to the back end data. A vast number of web sites may benefit mobile enablement.

FIG. 1 is an overview of a method for enabling existing web sites to be mobile, e.g., converting a web application to a mobile application or hybrid mobile application in one embodiment of the present disclosure. Briefly, a native application refers to an application that is developed to run a specific platform, e.g., using one or more resources, e.g., operating system specific to that platform. Similarly, a native mobile application refers to an application written to run on specific mobile device. On the other hand, platform independent codes or program such as those written in JAVA or the like may be written once and run anywhere. A hybrid mobile application refers to an application comprising both native and platform independent codes, e.g., platform independent code wrapped inside a native container. The method may include separating a web application into a static content and a dynamic content with data sources at 102. For example, the dynamic content may include one or more data sources from which to retrieve data at run time of the web application. The method may further include rendering the static content as HTML pages with the links between the HTML pages converted to local links and references to dynamic content changed to REST requests at 104. In one embodiment, the code may be separated into modules. For example, the HTML containing the static content and then an import of a JavaScript library may be referenced in the static HTML page to make the REST calls to obtain the dynamic data, enabling one or more REST requests from the HTML page. The REST requests may be also inserted to the HTML pages. The method may also include packaging the HTML pages as a mobile application that can be down loaded from an application store to a mobile device at 106.

The method may further include utilizing a mobile gateway on a remote server for accessing the dynamic content with the data sources at 108. The application further may include a native library for accessing device specific features, application code, JavaScript, HTML, cascading style sheets (CSS), RESTful interfaces for each dynamic tag, and other application artifacts, e.g., icons, images, and/or an application manifest indicating version information for each component of the application. Thus, in one embodiment of the present disclosure, an application may comprise a set of resources, e.g.: 1) static HTML resources representing the view; 2) JavaScript resources to make the REST calls; 3) JavaScript resources that bridge to the native API calls (this is hybrid); 4) native libraries; 5) CSS resources for formatting and styling the HTML.

The method may also include at 110, utilizing the application manifest for identifying component difference between a local version of the mobile application on a mobile device and a remote version of the mobile application resident on a remote server. The method may further include at 112, updating the mobile application selectively by only updating the HTML and JavaScript of the local mobile application with the changes from the remote version.

As one example, dynamic content that is represented in a Web 1.0 style application, e.g., Groovy Templates, JSP and PHP, may be modeled. In that way, the dynamic aspects can be extracted from the static components of the web page creating a static html version of the application that can be hosted by any “web server”. With the extracted dynamic components, the methodology of the present disclosure in one embodiment may use this model (data model associated with dynamic content of the web application) to generate a REST API for obtaining this dynamic data. An advantage of this solution is that by separating the HTML from the dynamic content, intermediaries can cache the static HTML resources and leverage the REST protocol for caching any of the services that are exposed via the REST API for the various CRUD operations (CREATE, RETRIEVE, UPDATE, DELETE).

A “web server” in the present disclosure refers to any server that is capable of file serving of static html resources (e.g., webkit containers for hybrid mobile applications such as PhoneGap™ or typical web servers such as Apache™), e.g., via hypertext transfer protocol (HTTP) requests, versus an application server such as WebSphere™ Application Server serving content such as JSPs or CGI plugins that can be used for executing script based languages such as PHP on Apache.

FIG. 2 is a flow diagram illustrating a method of converting dynamic content of a web application to a model such as RESTful data model based resources in one embodiment of the present disclosure. FIG. 3 is an example form field that allows users to update their profile. This example illustrates using a very simple HTML form to help describe how this could be done. This is by no means limited to this simple use case but it should help describe how this could be implemented. In this example, the sample JSP page contains a standard JavaBean that contains user profile information. This JSP is composed of mostly HTML content with some input fields that are populated by data retrieved by the JavaBean (POJO). A web page or application may utilize other dynamic components, e.g., other reusable software component not limited to JavaBean, and others.

In this code snippet, for example, the dynamic aspects are identified by the syntax defined by JSPs (and similar notions exist in PHP as well). In this code snippet, there are two types of JSP tags. The first is <% %> which allows one to insert scripts (also referred to as code snippets) and the <%=%> which allows one to output dynamic content (which, e.g., does not have to be visually displayed in the browser (e.g., it could be used for calculations in javascript for instance)). These hints are used to automatically extract the elements and generate, e.g., a RESTful Asynchronous Javascript and XML (AJAX) call to obtain the values from the server.

Referring to FIG. 2, at 202, the content of a web application document may be parsed to build a map of dynamic code references. The parsing of the document is performed to locate any dynamic content. In the example shown in FIG. 3, the method of the present disclosure may find one scriptlet that retrieves a ProfileBean object based upon the logged in user. For example, remoteUser contains the user subject's log in identification (id). Once this bean is instantiated, the form will reference this bean to provide the current values that it has for that user.

At 204, data model is generated based on the map of dynamic code references (also referred to as a reference map). The data model, e.g., specifies the variable names or object names that needs to be dynamically resolved at runtime. FIG. 4 illustrates an example data modeled in JavaScript Object Notation (JSON) to denote the attributes associated with the REST request.

At 206, client code (application) or client-side code is updated to retrieve and update dynamic content via REST. Using the data model defined at 204, the method of the present disclosure in one embodiment refactors the web resource (application) or the code to remove the references to dynamic scripting that is executed on the server side. In this example, Dojo may be leveraged to invoke a REST application program interface (API) that is running on the server to obtain the ProfileBean that has been modeled at 204. In response to receiving the content from the server, the method of the present disclosure in one embodiment dynamically via JavaScript updates the various form fields that had previously been populated server side.

FIG. 5 illustrates an example of an updated client (application) based upon the parsed data model. The example code replaces the dynamic content in the code shown in FIG. 3. Lines 8-22 of the example code show invoking of REST to obtain the ProfileBean.

At 208, server code is implemented to expose data model via REST. FIG. 6 illustrates an example of REST API for retrieving data based upon the model. The method of the present disclosure in one embodiment creates a RESTful resource implementation that can retrieve the content. In this example, a servlet is wired as the RESTful resource. In this code, the ProfileBean is retrieved and populated based upon the logged in user. Once this action is performed, the content is transformed to XML and returned to the user.

The following illustrates an example of the content that is returned:

GET /resources/profileBean result: { “firstName” : “Tom”, “lastName” : “Smith”, “email”: “tom.smith@xxx.com”, “sex” : “MALE” }

FIG. 7 is a diagram illustrating a mobile application packaged according to one embodiment of the present disclosure. A native library 702 comprises executable objects that can run on a mobile device. The native library 702 is used to access the device specific features. An application code 704 that has been converted from the web application performs its functions on the mobile device, and for example, may invoke one or more of functions of the native library 702. The application code may also utilize JavaScript, HTML, and/or CSS 706 executable on the mobile device. RESTful interfaces 708 for each dynamic tag is used to obtain the dynamic data from the web server. HTML file 710 contains static content of the code 704. Other application artifacts 712 such as icons, images, and others may be used in invoking the mobile application. In one aspect, the application code 704 comprises basic conversion from using web 1.0 styling or the like with JSPs to the RESTful or the like; The application code at 706 extends the code at 704 to also include the ability to use the native device APIs. The application code 706 may be further enhanced for a mobile device.

The entire contents may be packaged and deployed on an application store or the like that can be downloaded and installed on mobile devices. This helps the user to not have to retrieve every page from a server (since it is all packaged as part of the app) and the application feels like a native application.

In one embodiment of the present disclosure, such mobile application so deployed on a mobile device may be selectively updated, e.g., in optimized fashion. For instance, when an enterprise or like wants to update the mobile app, the enterprise can do so by the traditional way of packaging the entire mobile app and uploading to the application store and allowing the users download the entire app again to their devices.

Another way of updating a mobile app is to selectively update it. In one embodiment of the present disclosure, as part of packaging the mobile app, for example, an app manifest is added that has the information on the version of each component of the app.

An example of an appManifest is shown below:

appManifest applicationVersion : version number page1Version : version number page2Version : version number ... nativeLibraryVersion : version number

A mobile application may be deployed to an application store and also to a mobile server. The mobile server may run within the enterprise and services the enterprise's mobile applications to its users. When users want to install the application initially, they go to the application store to install it, e.g., the application is downloaded from the application store and deployed onto the user's mobile device. FIG. 8 is a flow diagram illustrating a method in which mobile apps installed on a mobile device may be updated in one embodiment of the present disclosure. At 802, a mobile application running on a mobile device may connect to a mobile server or the like, e.g., run by an enterprise providing the mobile application to its customers or users. At 804, the mobile application downloads an app manifest file associated with the mobile application from the mobile server or the like. At 806, it is determined whether the version number associated with the application specified in the downloaded app manifest file different from the current mobile application's version number, e.g., by examining the version number specified in the app manifest file previously downloaded and stored on the mobile device. If the application version number is different, at 808, one or more components that have different version numbers are determined, e.g., by comparing the content of the downloaded app manifest file with the previously downloaded one.

In one embodiment of the present disclosure, one or more components that have different version numbers may be downloaded, and stored locally on the mobile device at 810, which has the effect of updating the mobile application immediately. Further, at 814, the app manifest file is updated with one or more version numbers corresponding to the one or more downloaded components.

In another embodiment of the present disclosure, one or more components that have different version numbers may be marked at 812. At 816, when or in response to detecting a user navigating to, or using, the marked component of the mobile application, the component may be updated by downloading it from the application store. The app manifest file is also updated with the version number of the downloaded and updated component.

The app manifest file need not be limited to the format shown above. For instance, the app manifest file need not be one file containing information about all of the components; rather, there may be an app manifest file for a component. Other format may be utilized as app manifest file.

With the method shown in FIG. 8, it becomes very easy to update parts of the mobile application. The application still looks and feels like a native application since all the HTML, JavaScript, CSS needed are packaged as part of the app and the user does not have to wait to download the artifacts every time. The mobile app provider can not only upgrade but also rollback changes easily by updating the artifacts hosted in the mobile server within the enterprise.

This method also provides the ability for the provider to selectively open up functionality to different sets of users. Depending on the user credentials, parts of the application can be updated to provide new features.

FIG. 10 illustrates an architectural overview of mobile enablement of web sites in one embodiment of the present disclosure. A web site 1002 or a web application that displays or presents such site may be converted into a mobile application, e.g., as described above. The mobile application so converted may be stored in an application store 1004. One or more mobile devices (e.g., 1010, 1012) may download the mobile application from an application store or the like 1004, e.g., over a network 1008. Updates to one or more components of the mobile application associated with web site 1002 may be performed via a mobile server or gateway 1006. Such server or gateway 1006 may store or retrieve the updated components which may be downloaded to a mobile device, e.g., 1010, 1012.

FIG. 9 illustrates a schematic of an example computer or processing system that may implement the system that provides mobile enablement of web site in one embodiment of the present disclosure. The computer system is only one example of a suitable processing system and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the methodology described herein. The processing system shown may be operational with numerous other general purpose or special purpose computing system environments or configurations.

System memory 16 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) and/or cache memory or others. Computer system may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 18 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (e.g., a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 14 by one or more data media interfaces.

Computer system may also communicate with one or more external devices 26 such as a keyboard, a pointing device, a display 28, etc.; one or more devices that enable a user to interact with computer system; and/or any devices (e.g., network card, modem, etc.) that enable computer system to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces 20.

Still yet, computer system can communicate with one or more networks 24 such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 22. As depicted, network adapter 22 communicates with the other components of computer system via bus 14. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system. Examples include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.

As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.
